Improvement in shuttles for looms

WARREN WILDER, OF WILKINSONVILLE, MASSACHUSETTS.

IMPROVEMENT'IN SHUTTLES FOR LOOMS.

Specification forming part of Letters Patent No. 43,877, dated August16, 1864.

To all trhom it may concern Be it known that I, WARREN WILDER, ofWilkinsonville, in the county ot' Worcester and State ot' Massachusetts,have invented certain new and useful Improvementsin Shuttles for Looms;and I do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of thesame, referencebeing had to the accompanying drawings, in which- Figure l represents alongitudinal,vertical, section through said shuttle; Fig. 2 represents asimilar section through the shuttle, showing the spindle in an elevatedposition on which it is set when the bobbin is applied to or ri movedfrom it.

My invention relates to the combination of a spring-plate with the headof the spindle, whereby the latter is held in its proper position whilethe shuttle is in oprration,and

which permits ofthe spindle being turned for the purpose of applying toor removing from it the bobbin.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A represents the shuttle. B represents the spindle, and C the bobbin.The head a ofthe spindle turns on a pivot, b, and is extended to therear, as shown at c, said end or heel resting firmly upon theshuttle-Wood. A spring-catch, D, is secured to the heel c by means ofscrew in, and its end extends into the groove d of the bobbin-head e andkeeps the bobbin in its position on the spindles when the shuttle is inoperation.

The spindle-head a is extended above, as shown at 2, and a spring-plate,E,Wl1ieh is secured to the shuttle by means of screw g, presses upon theupper part ot' the spindlehead at 2, which latter is thus kept perfectlyrigid when the spindle is down in the shuttle. The spring E does notrest in its entire length on the shuttle-wood but only near its outerend, While the inner end presses upon the spindlehead. This leaves aspace between the spring E and the shuttle-wood, and by adjusting thescrew g the tension of the spring is regulated.

Gr represents a pin, which is passed-through the shuttle-wood betweenthe spring-catch D and the heel o. ln turning the spindle up to removethe bobbiu it is turned on the pivot b. This causes the pin Gto pressonthe-catch D, which is thus pushed out of the groove d of thebobbin-head, so as to release the latter. Meanwhile, 'the point 2 ot'the spindle-head passes under the spring E until the end ot' said springcomes in contact with the spindle B, and the motion of the latter isarrested and the several parts assume the positions represented in Fig.2.

This arrangement is a great improvement on those used heretofore, onaccount ofthe simplicity of its construction and because all the partsare on the outside of the shuttle and can be adjusted thereon Withouttaking the shuttle to pieces. Besides, thcadj u'stability ot' thespringE presents a great advantage over those devices Where springs areused on the inner parts of the shuttle to obtain a similar result.

This shuttle can also be used for weaving' from cops by simply removingthe springcatch I), which holds the bobbin, while all the other partsremain in the saine arrangement as above described.

Having thus fully described the nature of my invention, what I cla-imherein as new, and desire to secure by Letters Patent, is-

1. The combination of the spindle-head a with the heel c, upperextension, 2, springplate E, pivot G, spring-catch D, when constructedand arranged as herein described.

2. The combination of the top spring, E, Wi th the extended head 2 andprojecting heel c ofthe spindle-head, substantially as and for thepurposes described.

WARREN WILDER.
